Does anyone know if is ok to build walls/ceiling around a 480vac bus duct system as long as access is provided to the bus plug disconnects by removing ceiling tiles?
For example, just remove a ceiling tile if the bus plug disconnect needed to be locked out?
I need to write a short description for the following types of medium voltage switchgear panels:
Incomer Feeder Panel
Bus Riser Panel
Bus Coupler Panel
Direct Incomer Panel
So far my google searches haven't yielded anything useful. Could anyone please point me to any...
